A Novel Landscape Of Nuclear Human Cdk2 Substrates Revealed By In Situ Phosphorylation., Yong Chi, John H Carter, Jherek Swanger, Alexander V Mazin, Robert L Moritz, Bruce E Clurman

Articles, Abstracts, and Reports

Cyclin-dependent kinase 2 (CDK2) controls cell division and is central to oncogenic signaling. We used an "in situ" approach to identify CDK2 substrates within nuclei isolated from cells expressing CDK2 engineered to use adenosine 5'-triphosphate analogs. We identified 117 candidate substrates, ~40% of which are known CDK substrates. Previously unknown candidates were validated to be CDK2 substrates, including LSD1, DOT1L, and Rad54. The identification of many chromatin-associated proteins may have been facilitated by labeling conditions that preserved nuclear architecture and physiologic CDK2 regulation by endogenous cyclins. Candidate substrates include proteins that regulate histone modifications, chromatin, transcription, and RNA/DNA metabolism. Many …

Assay Development For Isolation And Characterization Of Anticancer Properties Of Marine Fungi, Kyra Ricci

Honors Theses

Metabolites from fungi have potential use in the drug discovery process and have been used in the past to develop therapeutic agents for human use. Initial characterization of potential therapeutic properties of fungi is thus an important first step in identifying novel therapeutic compounds. In the present study, marine fungi were isolated from Myrtle Beach and assayed for anticancer properties using the soft agar colony formation assay in a 3D in vitro cellular environment. Many species were isolated from environmental samples, displaying unique morphologies and growth patterns. To optimize the soft agar assay in a six-well cell culture plate for …

Diversity Of The Major Histocompatibility Complex In African Penguins (Spheniscus Demersus) In Situ, Athena Schalk

Undergraduate Honors Thesis Projects

The Major Histocompatibility Complex (MHC) is responsible for the immune response in all jawed vertebrates and protects individuals against a variety of pathogens and diseases. Maintaining genetic diversity within the MHC exons is critical to protecting endangered species. African penguins (Spheniscus demersus) are in danger of losing their MHC diversity in isolated populations due to reductions in population size associated with environmental changes and human activity. This study analyzes the diversity within the exons in the DNA encoding the MHC by amplifying the exons through polymerase chain reaction and identifying alleles through denaturing gradient gel electrophoresis. Wild populations of …

Conservation Of Bta-Mir-29b And Its Effect On Human Gene Expression, Anna Barent, Katie Meinders, Daniel Gutzmann, Audrey L. Atkin

UCARE: Research Products

The purposeof this work was to examine conservation of miR-29b and its binding sites in target mRNAs as well as co-expression of bta-miR-29b in bovine milk exosomes and its target mRNAs in HEK293 cells

•miRNAs are often highly conserved across species and bind to target mRNAs resulting in decreased gene expression. •Bovine milk exosomes contain miRNAs and most of these miRNAs are identical to human miRNAs. •Because these miRNAs are so conserved, it is hypothesized that bovine miRNAs can regulate gene expression and be linked to disease risk.

•miR-29b is highly conserved. •Identified 17 experimentally validated miR-29b target mRNAs. •The …

Tip60 Regulation Of Δnp63Α Is Associated With Cisplatin Resistance, Akshay Hira, Andrew Stacy, Jin Zhang, Michael P. Craig, Madhavi Kadakia

Celebration of Undergraduate & Graduate Research, Scholarship, and Creative Activities Materials

About 5.4 million basal and squamous cell skin cancers are diagnosed every year in the US. ΔNp63a, a member of the p53 transcription factor family, is overexpressed in non-melanoma skin cancer and regulates cell survival, migration and invasion. TIP60 is histone acetyltransferase (HAT) which mediates cellular processes such as transcription and the DNA damage response (DDR). Previous studies in our lab have shown that overexpression of TIP60 induces ΔNp63a protein stabilization in a catalytic-dependent manner. Since ΔNp63a is known to transcriptionally regulate several DDR genes and promote cisplatin resistance, its stabilization by TIP60 may contribute to the failure of platinum-based …

Assessing Seed Handling Processes To Facilitate A Community-Engaged Approach To Regional Forest Restoration, Meredith Cobb, Michaela J. Woods, Ryan Mcewan

Biology Faculty Publications

In the Midwestern United States, there is a strong management impetus toward reforestation to replace trees lost to due to tree mortality and to establish forests on previously cleared properties. Here, we describe a public outreach and volunteer effort that aimed to generate positive, community-engaged restoration outcomes and report on a practical experiment involving seed handling. We obtained tree seeds that were donated by members of the community to local land managers. We evaluated the size of the seeds collected and tested the influence of common stratification media (none, sand and vermiculite) and seed size on germination success of three …

Checkmate: Exploring Father-Son Communication Regarding Reproduction And Sexual Health In Males With Cystic Fibrosis, Dianna C. Sanderson

Theses and Dissertations

Cystic fibrosis (CF) is a heritable monogenic condition with allelic heterogeneity. A variety of sequence alterations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene results clinically in multisystem disease including a reduced reproductive capacity in affected males. Knowledge of reproductive capacity is often disclosed to parents by medical providers and to affected male children by medical providers and their parents. Despite advanced technology and therapeutics yielding the benefits of increased life expectancy and quality of life, males affected with CF largely remain uninformed in broader areas of sexual health and particularly in how their concept of masculine …

Elucidating The Regulon Of A Fur-Like Protein In Mycobacterium Avium Subsp. Paratuberculosis (Map), Fernanda Miyagaki Shoyama, Taveesak Janetanakit, John P. Bannantine, Raul G. Barletta, Srinand Sreevatsan

Nebraska Center for Virology: Faculty Publications

Intracellular iron concentration is tightly regulated to maintain cell viability. Iron plays important roles in electron transport, nucleic acid synthesis, and oxidative stress. A Mycobacterium avium subsp. paratuberculosis (MAP)-specific genomic island carries a putative metal transport operon that includes MAP3773c, which encodes a Fur-like protein. Although well characterized as a global regulator of iron homeostasis in multiple bacteria, the function of Fur (ferric uptake regulator) in MAP is unknown as this organism also carries IdeR (iron dependent regulator), a native iron regulatory protein specific to mycobacteria. Computational analysis using PRODORIC identified 23 different pathways involved in respiration, metabolism, and virulence …

Distortion Of The Local Magnetic Field Appears To Neither Disrupt Nocturnal Navigation Nor Cue Shelter Recognition In The Amblypygid Paraphrynus Laevifrons, Daniel D. Wiegmann, Patrick Casto, Eileen Hebets, Verner P. Bingman

Eileen Hebets Publications

Many arthropods are known to be sensitive to the geomagnetic field and exploit the field to solve spatial problems. The polarity of the geomagnetic field is used, for instance, as an orientation cue by leafcutter ants as they travel on engineered trails in a rainforest and by Drosophila larvae as they move short distances in search of food. A ubiquitous orientation cue like the geomagnetic field may be especially useful in complex, cluttered environments like rainforests, where the reliability of celestial cues used to navigate in more open environments may be poor. The neotropical amblypygid Paraphrynus laevifrons is a nocturnal …

Evaluating Pregnancy Outcomes Of Abnormal Non-Invasive Prenatal Screening Results In A High Risk Obstetrics Practice, Olivia Kesler

Theses and Dissertations

Non-invasive prenatal screening (NIPS) has rapidly grown in uptake since its introduction to clinical practice in 2011. In contrast to more traditional methods of screening, NIPS is the first to utilize cell-free fetal DNA for risk assessment of chromosomal aneuploidy and other conditions. Clinical validity has been established for the most common autosomal aneuploidies (Trisomy 21, Trisomy 18, and Trisomy 13) and sex chromosome aneuploidies, though some laboratories screen for conditions beyond these. A screen positive does not always indicate a true positive, therefore professional guidelines recommend diagnostic testing for confirmation and informed decision making on pregnancy management. Furthermore, the …

Assessing Social Media For Themes Of Trisomy 18 And 13, Falecia Metcalf

Theses and Dissertations

Themes within virtual communities have been explored examining topics such as prenatal diagnosis and termination for fetal anomalies, and it is known that when receiving a diagnosis of trisomy 18 or 13 parents may turn to online resources for information and emotional support. Knowledge of what content patients may encounter on various social media platforms about prenatal testing for trisomy 18 and 13 at large has not yet been established. However, this information would aid healthcare professionals in providing anticipatory guidance for patients using social media.

This study is a preliminary scan of social media to identify content areas and …

The Utility Of Whole Exome Sequencing In Patients With Intellectual Disability And Developmental Delay As A First-Tier Diagnostic Testing Strategy, Ellen Richardson

Theses and Dissertations

The purpose of this study is to evaluate the diagnostic utility of whole exome sequencing (WES) in patients with intellectual disability (ID) or developmental delay (DD), and to determine which patients may be the best candidates for WES as a first-tier diagnostic test. The diagnostic and clinical utility of WES has emerged to be greater than that of karyotype and chromosomal microarray for patients with ID or DD of unknown etiology, which are currently recommended as first-tier diagnostic tests for these patients. The emergence of next generation sequencing has led to more rapid identification of rare and novel genetic disorders. …

Revisiting The Essential Informational Needs Of Parents Receiving A Diagnosis Of Down Syndrome, Margaret Jean Wilkes

Theses and Dissertations

Down syndrome is a condition characterized by varying degrees of intellectual disability (ID), distinctive facial appearance, and congenital anomalies that results from the presence of a third 21st chromosome. Down syndrome is the most common chromosomal condition, affecting approximately 12.6 per 10,000 live births in the United States, making it imperative that we determine which information is most essential to impart to parents when first presenting the diagnosis. The aim of the present study is to reassess the informational needs of parents during the presentation of a Down syndrome diagnosis. In 2009, data were collected to define the essential information …

Journal of Bioresource Management

Arthritis is a chronic inflammatory disease that causes severe joint pain. Interleukin 17F (IL17F) is considered as a candidate gene functionally; it mediates pro-inflammatory responses, depending on the type and site of inflammation. The present study examined the polymorphism of IL17F (rs763780 and rs2397084) among the families affected by arthritis. Demographic data and blood samples were collected from the families with at least one affected offspring with arthritis. Analysis of the IL17F gene polymorphism was performed by the digestion of DNA with NlaIII and AvaII. The results showed that IL17F rs763780 (AA, AG and GG genotypes) and rs2397084 (AA, AG …

Accumulation Of Unacetylatable Snf2p At The Ino1 Promoter Is Detrimental To Remodeler Recycling Supply For Cup1 Induction, Michelle Esposito, Goldie Libby Sherr, Anthony Esposito, George Kaluski, Farris Ellington, Chang-Hui Shen

Publications and Research

Chromatin structure plays a decisive role in gene regulation through the actions of transcriptional activators, coactivators, and epigenetic machinery. These trans-acting factors contribute to gene expression through their interactions with chromatin structure. In yeast INO1 activation, transcriptional activators and coactivators have been defined through intense study but the mechanistic links within these trans-acting factors and their functional implications are not yet fully understood. In this study, we examined the crosstalk within transcriptional coactivators with regard to the implications of Snf2p acetylation during INO1 activation. Through various biochemical analysis, we demonstrated that both Snf2p and Ino80p chromatin remodelers accumulate …

Generating High Quality Libraries For Dia Ms With Empirically Corrected Peptide Predictions., Brian C Searle, Kristian E Swearingen, Christopher A Barnes, Tobias Schmidt, Siegfried Gessulat, Bernhard Küster, Mathias Wilhelm

Articles, Abstracts, and Reports

Data-independent acquisition approaches typically rely on experiment-specific spectrum libraries, requiring offline fractionation and tens to hundreds of injections. We demonstrate a library generation workflow that leverages fragmentation and retention time prediction to build libraries containing every peptide in a proteome, and then refines those libraries with empirical data. Our method specifically enables rapid, experiment-specific library generation for non-model organisms, which we demonstrate using the malaria parasite Plasmodium falciparum, and non-canonical databases, which we show by detecting missense variants in HeLa.

Care: Collecting And Assessing Cancer Family History To Identify At Risk Individuals Educational Intervention For Community Health Workers, Laura Moreno

USF Tampa Graduate Theses and Dissertations

Background: Collection of family health history (FHH) can identify individuals at increased risk and guide disease-specific recommendations for management, early detection, and prevention. Yet, collection of FHH is often low or infrequent despite national initiatives. In the Hispanic/Latino population, community outreach and education professionals (CORE-Ps) have effectively increased cancer prevention and control behaviors; but, limited research has been conducted to assess genetic and family health history knowledge among CORE-Ps. We sought to evaluate an educational program designed to improve cancer FHH and cancer genetics knowledge, self-efficacy and attitudes. Methods: The ARBOLES Program educates bilingual (Spanish-English) CORE-P to increase knowledge about …

The Sineb1 Element In The Long Non-Coding Rna Malat1 Is Necessary For Tdp-43 Proteostasis, Tuan M Nguyen, Elena B Kabotyanski, Lucas C Reineke, Jiaofang Shao, Feng Xiong, Joo-Hyung Lee, Julien Dubrulle, Hannah Johnson, Fabio Stossi, Phoebe S Tsoi, Kyoung-Jae Choi, Alexander G Ellis, Na Zhao, Jin Cao, Oluwatoyosi Adewunmi, Josephine C Ferreon, Allan Chris M Ferreon, Joel R Neilson, Michael A Mancini, Xi Chen, Jongchan Kim, Li Ma, Wenbo Li, Jeffrey M Rosen

Faculty, Staff and Students Publications

Transposable elements (TEs) comprise a large proportion of long non-coding RNAs (lncRNAs). Here, we employed CRISPR to delete a short interspersed nuclear element (SINE) in Malat1, a cancer-associated lncRNA, to investigate its significance in cellular physiology. We show that Malat1 with a SINE deletion forms diffuse nuclear speckles and is frequently translocated to the cytoplasm. SINE-deleted cells exhibit an activated unfolded protein response and PKR and markedly increased DNA damage and apoptosis caused by dysregulation of TDP-43 localization and formation of cytotoxic inclusions. TDP-43 binds stronger to Malat1 without the SINE and is likely 'hijacked' by cytoplasmic Malat1 to the …

USF Tampa Graduate Theses and Dissertations

Reasons for limited ethnic and racial diversity among genetic counselors in the United States may be elucidated through better understanding the experiences of minority students who are attending genetic counseling graduate programs as well as recent graduates. Semi-structured interviews were conducted with minority participants using Journey Mapping to elicit touchpoints that positively or negatively impact success at varying points on the path to becoming a genetic counselor. Touchpoints with negative impacts include; late awareness of the profession, observing the lack of diversity in the field, the financial burden of the application process, and microaggressions from peers, program leadership, and clinical …

Terms Of Service: The Use And Protection Of Genomic Information By Companies, Databases, And Law Enforcement, Sophia Kallas

Honors Program: Senior Projects (Public)

Private genomic companies have become a popular trend in the last two decades by providing customers with information regarding their ancestry and health risks. However, the profiles received from these companies can also be uploaded to public databases for various purposes, including locating other family members. Both testing companies and public databases have private interests, and both are at risk of law enforcement intervention for the purpose of forensic familial searching. There is little federal legislation protecting the privacy of an individual’s genetic profile. Consequently, it has been up to federal agencies, state laws, and judicial precedents to prevent the …

Evaluating Effects Of Cancer Genetic Counseling On Several Brief Patient Impact Measures, Alyson Kneusel

USF Tampa Graduate Theses and Dissertations

Many outcomes for assessing cancer genetic counseling (GC) utility have been proposed, with few studies evaluating multiple, theory-based, brief patient-reported experience and outcome measures simultaneously as part of a single study. We conducted a pilot study in which patients seen for pre-test cancer GC took a survey before and after their GC session to evaluate the session’s impact on multiple patient impact measures and assess the relationship between these measures. Measures based on the self-determination theory (SDT) assessed three basic needs including: 1) perceived autonomy support, 2) relatedness to the provider, and 3) competence to make a decision. SDT posits …
